PHYSICS-BASED DIGITAL TWIN AND SURROGATE-MODEL OF A HYDROGEN-BLEND COMBINED CYCLE GAS TURBINE WITH POST-COMBUSTION CARBON CAPTURE THIS PROJECT AMBITIOUSLY TARGETS THE DEVELOPMENT OF AN INNOVATIVE DIGITAL TWIN FRAMEWORK, SPECIFICALLY DESIGNED FOR INTEGRATED HYDROGEN-BASED SYSTEMS WITH CARBON CAPTURE, DIRECTLY CORRESPONDING WITH AREA OF INTEREST 20'S EMPHASIS ON ADVANCING ENERGY SYSTEMS THROUGH INNOVATIVE DIGITAL SOLUTIONS. THE AIM IS TO ENHANCE OPERATIONAL EFFICIENCY, OPTIMIZE FLEXIBLE OPERATIONS, AND SUPPORT THE TRANSITION TO CLEAN ENERGY TECHNOLOGIES. THE PROJECT WILL CREATE INTO A COHESIVE HYDROGEN FUEL BLEND, GAS TURBINE COMBINED CYCLE WITH CARBON CAPTURE (H2-GTCC-CC) DIGITAL TWIN MODEL FOR USE BY THE ENERGY COMMUNITY TO ASSESS THE NET ZERO CAPABILITY AND PERFORMANCE OF NEW AND EXISTING GTCC PLANTS WHEN OPERATED WITH HYDROGEN FUEL BLENDING AND CARBON CAPTURE UNDER FLEXIBLE OPERATIONS.
